You can apply a patch by using the MapR Installer, by using the command line (a manual process), or by using a MapR Installer
Stanza.

Customizing Your Deployment by Using the MapR Installer Web Interface

If you use a MapR offering or reference template, the cluster is installed for you
according to the parameters you specified. Another way to customize the resources and
services provisioned to a MapR cluster on AWS or Azure is to create a stack or resource
group with only the MapR Installer. Once the stack or resource group is created, you can
use the MapR Installer web interface to finish configuring the cluster.

This procedure
is the same for AWS and Azure:

Choose one of these procedures to create an AWS stack or an Azure resource
group:

When you run the template, fill in the MapR template values as described in one
of previous topics:

Important: In the provisioningTemplate field
(AWS) or Service Template field (Azure), select
Custom-Configuration for the Auto-Provisioning Templates. Selecting
Custom-Configuration instructs the template to
install only the MapR Installer and related software so that you can finish
the cluster installation on your own.

After stack creation (AWS) or resource group creation (Azure), log on to the
MapR Installer, and use the web interface and on-screen user assistance to
configure the resources and services you need in the cluster.

Note: For cloud-based installations, the MapR Installer displays
Authentication screens with cloud-specific
parameters that are different from the Authentication
screens for on-premise clusters. Use the tooltips on these screens to
understand the authentication information that you need to provide for your
cluster.
